HI the purpose of this topic is to collect as many as possible bash improvements and set t ings that live in your bash running config( ~/.bashrc*0 A few rules beforehand: - every thing posted should atleast a description for what it does - and the depencies it may or may not have if they arend part of coreutils and or the posix std. - !!!! NO FUNCTIONS !!! if you want to share a neat function , and its not user specific , you can still post it but make sure it can operate as - a stand alone shell script in /opt/bin/ or /usr/bin/ or allow for dropping in /etc/profile.d or /etc/bash/bashrc.d/ without requiring anyting more than a simple call from bashrc or a source instruction - please also separate the aliasses that are distro specific , into a seperate code block so people can copy whole sections without cluttering their env wit aliases that wont work on their system... - if you do need to store something in the env please try to use a bash array ifits more than a single variable, and prefix the variable with the corename of the thing. - for any code that creates new files on the system a procedure to remove all those files automaticly needs to be included , even as a part of an istaller or part of the make file ... eg -dont assume people have sudo installed just write the thing as if ran by root , if it fails when run as regular user , not a problem but an error complaining about permissions is easier fixed than an error about file not found. ill start of with my discoveries some of them really old : 2004+ some of them only recent additions and i wish i had known since the beginning.
